Description

TECHNICAL FIELD

[0001] The present application relates to the field of gas and aerosol disinfection, in particular to a ventilation type disinfection and deodorization toilet device. BACKGROUND

[0002] Excrement contains a large amount of bacteria and harmful odor, and a large amount of bacteria and harmful odor will be generated during the use of a toilet by a patient, especially a patient with infectious diseases. When the toilet is flushed, the water flow impacting the water surface will stir up fine water mist, and the fine fecal particles and water droplets in the toilet will be carried into the air to form aerosols. These aerosols can splash to an altitude of several meters, and the bacteria and viruses (such as Escherichia coli and Norovirus) in the aerosols will then be dispersed and settled on the surfaces of objects in the bathroom, such as toothbrushes, towels, floors, and the like.

[0003] At present, there are various antibacterial toilet devices, such as an antibacterial toilet cover and a preparation process thereof (CN115710404A), an antibacterial melamine toilet cover and a manufacturing method thereof (CN109929217A), a stainless steel nanometer antibacterial toilet (CN110629841A), and an antibacterial toilet (CN215829563U), etc. Generally, silver-zinc-copper zeolite antibacterial material or a mixture of nanometer titanium dioxide and nanometer zinc oxide powder is added in the manufacture of a toilet cover, or a nanometer antibacterial coating is sprayed on the surface of the toilet, or an inorganic silver antibacterial plastic toilet cover plate is used. These antibacterial toilets mainly use nanometer silver, zinc oxide and other inorganic antibacterial agents to destroy the bacterial cell structure, inhibit the growth of common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus on the surface of the seat ring, and reduce the cross-infection and spread of related bacteria such as diarrhea and skin infection caused by the use of the toilet by multiple people. The characteristics of these antibacterial toilets are mainly physical antibacterial, no chemical volatile substances, safe and non-toxic, and long-acting antibacterial effect.

[0004] There are also antibacterial toilets, such as an ultraviolet toilet disinfection cover (CN206403697U), which sets an ultraviolet disinfection device in the middle of the toilet cover. The rotation of the ultraviolet light source driven by the motor achieves comprehensive disinfection of the toilet cover and the interior of the toilet. The ultraviolet rays can destroy the DNA / RNA of bacteria to achieve a bactericidal effect.

[0005] There are also antibacterial toilets, such as a new type of sterilization and deodorization toilet cover (CN208259643U) and a deodorization device and a deodorization toilet (CN222782160U), which use "activated carbon adsorption deodorization", "ion deodorization", and "photocatalyst deodorization". These methods mainly adsorb or decompose the odor generated by the decomposition of organic matter by bacteria in the toilet, keep the air in the bathroom fresh, and reduce the discomfort of the human body caused by the odor.

[0006] However, the traditional antibacterial toilet does not have effective measures to solve the problem of harmful odor and aerosol overflow. The present application adopts a special scheme, first, the harmful odor is sealed in the toilet by air curtain, then the harmful odor is extracted to the disinfectant solution in the disinfection tank by the air extraction device, the water-soluble part in the harmful odor reacts with the disinfectant solution, and the rest of the water-insoluble part is adsorbed by the solid adsorption layer, so as to achieve the purpose of antibacterial and deodorization. SUMMARY

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] It should be noted that in the description of this invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to this invention.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a ventilated disinfection and deodorizing toilet includes: a base 1, a ventilated seat 2, a sensing device 3, a wire 4, a control device 5, a blower 6, an exhaust fan 7, a porous pipe 8, an outer wall of a disinfectant tank 9, a disinfectant chamber 10, a solid disinfection adsorption layer 11, and a sealed lid 12. The lower outer side of the ventilated seat 2 is fitted seamlessly with the upper inner side of the base 1. The air inlet pipe 2-1 on the upper part of the ventilated seat 2 is connected to the blower 6. The blower 6 forms an air curtain through several air holes on the side of the air inlet pipe 2-1. The exhaust fan 7 is connected to the air outlet pipe 2-2 on the lower part of the ventilated seat 2 through an exhaust pipe 7-1. The exhaust fan 7 is connected to the porous pipe 8 through an exhaust pipe 7-2. The exhaust fan 7 draws harmful odors from the toilet into the porous pipe 8 through several air holes on the side of the air outlet pipe 2-2.

[0026] Example 1:

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention relates to a ventilated disinfection and deodorizing toilet. Before use, the sealed lid 12 is placed horizontally so that the lower part of the sealed lid 12 fits against the upper part of the ventilated seat 2, forming a relatively sealed space. During use, the sealed lid 12 is first placed vertically at the rear of the base 1. The sensor 3 is connected to the control device 5 via the wire 4. When a person touches the sensor 3, the sensor 3 triggers the control device 5, which then starts the blower 6, forcing air into the air intake pipe 2-1 on the upper part of the ventilated seat 2. The air forms an air curtain through several air holes on the side of the air intake pipe 2-1, thereby isolating harmful odors inside the toilet. At the same time, the control device 5 starts the exhaust fan 7, which is connected to the exhaust pipe 2-2 on the lower part of the ventilated seat 2 via the exhaust pipe 7-1. The exhaust fan 7 draws the harmful odors in the toilet into the porous pipe 8 through several air holes on the side of the exhaust pipe 2-2.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the porous tube 8 has multiple exchange holes 8-1 on its surface. The bottom of the porous tube 8 is 2-5 mm away from the bottom surface of the outer wall 9 of the disinfectant tank, and the top of the porous tube 8 is 30-50 mm below the surface of the disinfectant in the disinfectant chamber 10. When pressurized harmful odor is drawn into the porous tube 8, it will enter the disinfectant chamber 10 through the multiple exchange holes 8-1. The water-soluble part of the harmful odor reacts chemically with the disinfectant in the disinfectant chamber 10, and the water-insoluble part of the harmful odor overflows from the disinfectant chamber 10 and is physically adsorbed by the solid disinfection adsorption layer 11 and undergoes a chemical reaction. The remaining gas overflows into the atmosphere through the solid disinfection adsorption layer 11, completing the harmless deodorization process.

[0029] like Figure 1 ,Figure 2 and Figure 3 As shown, in the present invention, the ventilated disinfection and deodorizing toilet, before flushing after use, the sealed lid 12 is placed horizontally so that the lower part of the sealed lid 12 fits against the upper part of the ventilated seat 2, forming a relatively sealed space. This confines the harmful aerosols generated by flushing within the relatively sealed space. Then, flushing begins. After flushing, the control device 5 controls the air extraction machine 7 and the blower 6 to run for a delay of several minutes to further clean up the harmful aerosols.

[0030] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content described in the specification, but is determined according to the scope of the claims.
